How big a household photovoltaic power generation system can be installed on your own roof?

Solar energy resources are very rich, and the annual irradiation hours can reach about 2,200 hours. From a geographical point of view, it is more suitable for installing household photovoltaic power generation systems. With the support of national policies, many people consult household photovoltaic power generation systems with high enthusiasm The issue of installed capacity is not unfamiliar now, and it is not a problem that can be explained in a sentence! Aspects to be considered when installing a household photovoltaic power generation system: The roof area, the area of u200bu200bthe house and the orientation of the house need to be considered. Of course, the main decision is the area of u200bu200bthe roof. Speaking of roofs, let’s talk about the current domestic roof types: cement roofs, color steel roofs, and tile roofs. The angle of installed capacity: horizontal roofs, sloping roofs. How to calculate the installed capacity for horizontal roofs? That is to say, the roof should be flat. When laying photovoltaic power generation panels on this type of roof, pay attention to the following: 1. Build supporting brackets and set the inclination angle according to the sunshine. 2. Because of the inclination, pay special attention to the distance of photovoltaic power generation panels to avoid obstructing the industry calculation method: 50 to 70 watt photovoltaic power generation panels can be installed on a horizontal roof of one square meter. Next, let's talk about the inclined roof, which covers the color steel roof and tile roof. When installing photovoltaic panels, it can be laid seamlessly according to the inclination of the roof. Note the following: 1. It is not necessary to lay the support and calculate the inclination angle. It can be laid according to the angle of inclination during installation. 2. When installing the color steel plate or tile, it is necessary to consider the weight of the installation roof and the waterproof measures of the roof.
